MECHANICAL MOVEMENT.

Speciicaton of Letters Patent.'l

Patented May 18, 1909.

Application filed March 25, 1908. Serial No. 423,119.

To all whom (it may concern:

Be it known that I, PHILIP T. MCNALLY, a citizen of the United States,residing at Mandan, in the `county of Morton and State of North Dakota,have invented a new and usei'ul Improvement in Mechanical Movements,olwhich the following is a specification.

My invention is in the nature of a novel mechanical movement, forconverting simple reciprocating motion into a modified reciprocatingmotion alternately in two diiierent planes, for various uses in thearts, and it consists in the novel construction and arrangement of thestationary frame provided with guides for the reciprocating member, incombination with a shifting switch acting automatically to direct themovement, as will be hereinafter more fully described with reference tothe drawing, in which- Figure l is a front view, and Fig. 2 an edge viewoi' the mechanical movement.y Fig. 3 is a centralr longitudinal section,showing theA position oi parts for directing .the reciprocating bodyinto one plane of actlon. Eig. 3a is a similar section, showing theposition ol' parts for directing the reciprocating body Fig. 4 is a Fig.5 is a longitudinal section o n line 5-5 of Fig. 1 and Fig. 6 is asectional detail of the auto-k into another plane oi' action. crosssection on line 1*4 of Fig. 1.

matic shifting switch.

In the drawing, A B B represent a stationary mainframe with its guides,O is the shift# ing switch, and E is the reciprocating member whoseplane oi reciprocation is directed alternately into the two paths of theguide slots h and h.y v

The main frame is composed oi a central piece A made wedge-shaped at oneend and supported exclusively at the other end by screws s s whichconnect it detachably between the two legs B B of the outer frameportion. l each side so as to form, between its sides and the outerframe, slots h h which at their lower ends converge and merge into thesingle guide slot r which preferably bisects the angle of convergence ofthe slots 71, and h equally, and, as shown, the slots h and h areparallel and the plane of the slot r is parallel to the slots 7L and hand if extended the plane of slot r would be equidistant from the slotsh and h.

The central piece A is recessed on The shifting switch O consists of atriangular metal block inserted in a slot in the wedge shapedend of thepiece A and pivotally connected thereto by a pin g. Within a recess inone apex oi' the switch block O is pivoted uponits pin g asymmetricallyiormed switch tongue c which is maintained normally in aline bisecting the apex of the switch by two yielding iingers a a, oneon each side or the tongue and bearing against it in oppositedirections. The upper ends of these yielding fingers are pivoted in therecess of the switch block and the two iingers are drawn together by thetension of an interposed spiral spring fi which through the fingers aaexerts an equal pressure upon opposite sides of the spring tongue cwhich holds it straight and true, but allows it to yield in eitherdirection.

The switch block O is capable oi tilting on its center. g, so as tocause its two upper corners to alternately extend across the guide.slots 7L and 7L and partially blockade the same. When the uppercornerof the switch block lies across the guide slot h, as seen in E ig. 3then the yielding switch ton ue c will be thrown across the other guides ot h just at the point where the two slots h h converge into .the slotr. In like manner when the switch block is tilted inthe other direction,as in Fig. 3a, so that its other upper corner lies across sloty h, sloth will be olpened above and will be closed below by t e tongue c.

The two positions to which the switch block C may bethrown aremaintained by a brake or yielding detent, consisting of an elasticcross-head y' mounted on the end of a yielding stem d, slidinglongitudinally in a central hole in the iece A and forced downwardly bya spira spring u arranged behindV the stem. The upper corners of theswitch block are. formed with notches n n and when the switch block isturned, it forces the spring cross-head y' and its stem d back until therounded portionI of one end ofthe cross-head drops into Vanotch n andthus xes and holds thev switch block in the )osition to which it may bethrown, until1 forcibly made to change its position again. Whensufficient force is applied to the switch block in the oppositedirection its notch n, pressing back the rounded end of the cross-head,causes the stem d to yield backward and let the notch pass and as theswitch goes to the limit of its shifting move=V and then in the other oftwo different planes.

Assuming that the pin` E is the reciprocating traveler whose pathis tobe changed' first into one plane and then into another', when the pin Erises and the switch is in the position shown in Fig. 3, it finds thetongue c lying across the entrance to the slot h. The pin E therefore inrising passes into the slot h across which the right hand upper cornerof the switch block is at this time lying. Said pin therefore strikesthis corner of the switch block and tilts it and its yielding tongueinto the dotted position in Fig. 3 and full line position of Fig. 3a.When the pin E descends it strikes the spring tongue c and, as thisyields to the left, the in passes by the same and down into the s ot r.Now on the next ascent of the pin E it finds the switch in the positionof Fig. 3el and as the pin rises its entrance to slot 7L is blocked bythe spring tongue c and said pin is therefore compelled to pass up theother slot h. As it rises therein it finds the left hand corner of theswitch block lying across the slot 7L', and, striking the same, shiftsthe switch on its center to the full line position of Fig. 3 again. ltwill thus be seen that the simple reciprocation of pin E, as or part ofa machine, causes it with my devices to alternately enter first one, andthen the other of the two paths` h and' h. As shown these paths areparallel, but it is obvious that they need not be so, but may beextended in any divergent directionfrom the slot r. l

ln the vedges of the device are formed slots t. These aredesigned togive passage to any two lever ends, pins, or other parts to which it maybe desired to transmit motion alternately. The ends of two such devicesin such case simply protrude through the slots t into the ath of thereciprocating member E, which a ternately acts first upon the device onone side and then upon the de'- vice on the other side. To render thismore clear, l. have shown in Fig.' 1, in dotted lines, a lever lfulcrumed in the middle and having at its ends pull rods 2 and 4 withiii-turned ends 3 and 5, which extend through the slots t into the pathof the reciprocating member E, the ends 3 and 5 being alter= natelylifted by said membervE. My device may be advantageously applied to theoperactuated by any prime mover ation of electric switches and invarious -other arts` where an-A alternate action is desired.
